This paper summarized the high yield cultivation technology for summer maize using dense planting and drip irrigation with integrated water and fertilizer management in Northern Anhui Province. Before sowing, maize varieties suitable for dense planting, such as Annong 218, are selected. Fine land preparation is carried out, and straw returning is implemented to enhance soil fertility. Precision sowing is performed before June 25 using a navigation-equipped seeder to complete direct seeding, fertilization, and drip tape laying in a single operation. Base fertilizer is applied through layered deep placement of maize-specific compound fertilizer at 40-45 kg/667 m2, accompanied by the installation of a precise drip irrigation system. Field management emphasizes accurate regulation of water and fertilizer, with staged drip irrigation and topdressing according to growth stages. Chemical control to prevent lodging is applied at the 6-8 leaf stage. Pest and disease control follows a prevention-first approach, and pesticides should be applied during the seedling stage, bell mouth stage, and tasseling and flowering stage to prevent rust, maize borer. Harvesting is conducted when the grain milk line disappears and moisture content falls below 28%, using high-performance combine harvesters. Post-harvest operations include grain drying, drip tape recycling, and straw returning. This technology system integrates superior varieties, dense planting, precise water and fertilizer management, and full mechanization to achieve high yield, efficiency, and green sustainable production in summer maize cultivation.
